Contribution: Significant gender differences are observed on primary school students' perception of self-efficacy and test anxiety in mathematics. Girls perceive themselves to be significantly worse than boys in mathematics and report higher test anxiety toward mathematics exams. Gender differences in self-efficacy become more pronounced as students grow up, and test anxiety increases for all students. However, the present study shows that teachers' do not perceive differences in self-efficacy in mathematics between boys and girls.

The development of phonological awareness, i.e. the metacognitive skill that allows thinking and manipulating the language structure, from an early age is mandatory for the acquisition of literacy skills. Multisensory stimulation, curiosity and interest are fundamental for learning. In doing so, Communication Technologies have a key role because a learning-oriented use can encourage current digital natives’ interest and thinking. This paper presents a game with tangible technology designed for both intervention and diagnostic, formative and summative evaluation. The user experience was carried out during two weeks through a multiple case study with four kindergarten children. A multimedia adventure game was presented in which they had to solve phonological awareness challenges through the manipulation of tangible technology to achieve the final goal. The observation was recorded in the designed evaluation model, allowing the analysis of pre- and post-intervention data after the triangulation of data for subsequent qualitative analysis. The results show an improvement in phonological awareness, as well as the gamified experience marks. These promising outcomes support the use of such methodologies to a learner-centered education model.

Whereas the demand of pure Science, Technology, Engineering and Mathematics (STEM) jobs is increasing, young people interested on STEM studies are decreasing. Among the reasons, different studies show that male and female students do not have a clear perception of engineering. Furthermore, there is a very worrying gender gap in fields as Computer Science. The lack of role models, stereotypes and the perception of a machine and programming oriented discipline are pointed out as possible reasons. In order to reverse the situation, this paper presents an ongoing project to be conducted at the early years of high school to connect computer engineering with environment giving the students the idea that computer engineering is not only about programming and giving them real-life applications. Then, the project serves of Internet of Things (IoT) and Sustainable Development Goals (SDG) to propose students a real world problem to face and promote engineering vocations. One of the key aspects of the project is to be directed to young students. This increases the impact in both number of students attending the activity and the possibility that teachers accomplish actions against the gender gap before it is well established.

There are many underground applications based on magnetic fields generated by an oscillating magnetic source. For them, a magnetic dipole in a three‐layered region with upper semi‐infinite air layer can be a convenient idealization used for their planning, development, and operation. Solutions are in the form of the well‐known Sommerfeld integral expressions that can be evaluated by numerical methods. A set of field expressions to be numerically evaluated by an efficient algorithm are not collected comprehensively yet, or at least in a directly usable form. In this paper, the explicit magnetic field solutions for the vertical magnetic dipole and the horizontal magnetic dipole for a general source‐observer location are derived from the Hertz vector. They can be properly combined to model the problem of a tilted magnetic dipole source for horizontally or inclined stratified media. As a result, a complete set of integral equations of the Sommerfeld type valid from the near zone to the far zone are formulated. A method for numerical evaluation of the field expressions for high accurate computations is described. The numerical results are validated using the finite element method for all the possible source‐receiver configurations and three well‐spanned frequencies of typical subsurface applications. Both numerical solutions agree according to the normalized root‐mean‐square error‐based fit metric. Numerical results for two cases of study are presented to see its usefulness for subsurface applications. A MATLAB implementation of the mathematical description outlined in this paper and the proposed evaluation method is freely available for download.
